Electrochemically Driven Assembly of Mixed Dithiol Bilayers via Sulfur Dimers

Electrochemically driven mechanical energy harvesting

Efficient mechanical energy harvesters enable various wearable devices and auxiliary energy supply. Here we report a novel class of mechanical energy harvesters via stress-voltage coupling in electrochemically alloyed electrodes. The device consists of two identical Li-alloyed Si as electrodes, separated by electrolyte-soaked polymer membranes. Bending-induced asymmetric stresses generate chemi...

Porphyrin dimers bridged by an electrochemically switchable unit.

In the past decade much effort has been devoted to the synthesis and studies of molecular systems comprising porphyrin units bridged by well-defined p-conjugated spacers at the mesoor b-positions. These conjugated oligoporphyrin systems are expected to have potential applications in molecular wires and electronic devices due to their unique optical, physical, and chemical properties. Photophysi...

1 Mixed Dimers of Insulin

Insulin degrading enzyme (IDE) exists primarily as a dimer being unique among the zinc metalloproteases in that it exhibits allosteric kinetics with small synthetic peptide substrates. In addition the IDE reaction rate is increased by small peptides that bind to a distal site within the substrate binding site. We have generated mixed dimers of IDE in which one or both subunits contain mutations...

Nuphar Dimers: Crouching Sulfur, Hidden Reactivity

The dimeric Nuphar alkaloids are a structurally unique family of natural products containing an unsymmetrical thiaspirane. These sulfur-containing alkaloids were first isolated from the fresh water plant Nuphar lutea by Achmatowicz in the early 1960s. The most potent member of the Nuphar dimer family (6-hydroxythiobinuphraidine, Figure 1) is a rapid inducer of apoptosis, exhibiting in vivo anti...
